'SOLE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 239,999, dated April1.2,

Application filed February 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOSHUA F. AMES, of Rockland,county of Plymouth, andState of Massachusetts, have invented a new and useful ImprovementinSole-Channeling Machines, of which the following description, inconnection with the accompanying drawings, is a specification.

This invention relates to improvements in mechanism for channeling andbeveling the inner sole for what is known as-a welted boot or shoe, andhas for its object the-production of a machine whereby the edge of thesole outside the wale may be made of the same thickness entirelyabontthe sole, notwithstanding variations in the thickness of the stock orthe inclination of the bevel between the edge of the sole and the outeredge of the wale, the said bevel being made at different angles atdifferent parts of the shoe, the bevel being carried in farther andbeing therefore less abrupt at and near the shank of the inner sole.

In this my improved machine the inner sole to be channeled and beveledhas its face placed on a support made as a wheel, and the upper side ofthe sole or stock, or that part which is to form the wale, is engagedand moved by a toothed feeding-wheel, which is so mounted that it mayyield vertically to adapt itself to varying thicknesses of the stock,the said feeding wheel or device moving the stock forward underpressers, and against the edges of a channel, and of a beveling cutteror blade, which remove from the stock, at each side of the Wale,

a proper amount of material to leave the Wale of the desired height, andthe edge of the sole of the desired thickness.

The bevelin g cutter or blade is adjnstably connected with a carriageheld and made movable in a curved path about amovablefulcrum-pin, sothat the movement of the said carriage nearly in the arc of a circlewill cause the edge of the cutter held in it to be presented at agreater or less angle of inclination with relation to that part of thesolesupporting surface on which the sole rests. .Astheinclinationofthisbeveling-cutteris changed from a horizontal planeparallel with the surface of the sole or support, the latter is alsoautomatically moved horizontally,so that the cutter when at its greatestinclination will not strike against the edge of the support, but mayalways be kept at the same relative distance my invention, thestock-support being shown as moved out somewhat toward the left into theposition it will occupy when the sole is being channeled and beveled atthe shank, about its fore part, toe, and heel, the carriage holding thebeveling-cutter being then thrown down into its lowest position. Fig. 2is a sectional detail of the carriage which holds the beveling-cutter,and of the guideway in which it moves and is guided. Fig. 3 is a detailin section of the bracket and bearing which holds the channel-cutter,and of the means for adjusting the said channel-cutter. Fig. 4 is anelevation of the opposite side of the machine from that represented inFig. 1, a part of the frame-work and support being broken away to bettershow their construction, the support occupyingaposition closer to theframe-work than in Fig.1,the position substantially which it will occupywhen the sole is being channeled and beveled about its shank,the beveling-cutter and its carriage beingthen elevated. Fig.5 is a partialvertical section in the line as, Fig. 1. Fig. 6 shows cross-sections ofa sole to be produced on my machine, the uppermost section being acrossthe fore part of the sole, and the lowerinost section across the shank;Fig. 7, a detail inside view of the guide-block in which the carriage ofthe beveling-outter moves; and Fig. 8 is a view of the interior of thecarriage for the beveling-cutter, but inverted.

The frame parts A A of the machine will be of suitable shape to supportthe working parts. The part A of the frame, made as an arm, is pivotedto the part A by the bolt A The arm A has an ear, A provided with astud, A, upon which is placed a pinion, A having connected with its huba handle, A, by which the machine is operated. This pinion A engages anddrives the toothed gears B G. The gear B is placed on shaft B, havingits bearings in the frame-arm A, while the toothed gear 0 is secured tothe shaft C, having its bearings in the frame part A.

Upon the forward end of the shaft 0 is placed the stock or sole support0 it being loosely connected therewith by a feather, a,

so that the said support may be moved longitudinally on the said shaft.The hub of the support 0 (see Fig. 4) receives aboutit the strong spiralspring 0 held in place thereon by a nut, 0 turned upon thescrew-threaded end of the shaft 0, so that the pressure of the saidspring tends to keep the support 0 pressed back against the roller a atthe end of the slidebar (i connected with the toggle-joint a 01. thecenter of which has attached to it the rod a", which in practice will beconnected with a suitable foot-treadle, (not shown,) the normalcondition -of the toggle-joint due to the pressure of spring 0 beingthat indicated in Fig. 4. The slide-bar a screw-threaded for a portionof its length, is provided with a nut, 2, which controls the extremeforward movement of the slide bar and roller a by abutting against arigid part of the frame-work, and also with nuts 3 4, which are made topinch the shank b of the edge-gage 5, made laterally movable with theslide-bar a and support 0 the body of the edge-gage being slotted, as

shown in Fig. 1, where the screws 6 6 extend through it, so as to permitthe edge-gage to move laterally and remain always in the same positionwith relation to the edge of the support 0 The arm A of the machine hasa downwardly-extended leg, A (Shown as broken out in Fig. 1, to clearlyexhibit the edge-gage, part of which is shown in section.) The lower endof this leg is received within a slot at the rear of an upright car, A,broken off in Fig. 1, but shown in detail, Fig. 5. This leg A of the armA, held down by the stress of the spring D on the rod d connected bybolt (1 with a backwardly-extended part, 90 of arm A, rests upon stop 61the latter thus controlling the descent of the arm A and the cutters andfeed-wheel carried by it.

. A lever, D, (see Fig. 1,) has its short end interposed below the legA, and when brought into the position shown in that figure acts upon thelower end of the leg and lifts the forward end of the arm A and itsattached parts, to permit the work to be introduced or removed.

The arm A has a depending bracket, D herein ,shown as connectedtherewith by a bolt, D, the said depending bracket having adjustablyjoined with'it the shank b which at its lower end has an adjustablebearing controlled by the screw b the said bearing 1) receiving the rodI), (see Fig.3,) which carries the channeling-cutter c, it being heldadjustably upon the said rod by the nut c, the said rod being madeadjustable longitudinally in its bearing by the adjusting-screw b, tothus place the acting edge of the cutter c in proper position withrelation to the forward end of the presser-foot d, connected with thebracket D by the screws 8 in such manner that the spring cl may act tohold the said presser in a yielding manner in contact with the solebeing channeled.

The channel cutter can be raised and lowered vertically with relation tothe support 0 and may be secured in proper adjusted position by means ofthe screws 01 (see Fig. 4,) according to the depth to which it isdesired to cut the channel and the descent of the lower end of the armA, which carries the cutters and feed-wheel, is regulated by the stop d(see Fig. 1,) against which the lower end of the leg A is permitted tostrike.

The channel-cutter 0, having been set to cut into the leather a certaindistance from the upper side of the sole to form the wale u, (see Fig.6,) cannot descend or cut into the stock or leather only to such adistance from its face, or that side of it resting upon the support 0 asshall be determined by the stop d so the bottom of the channel .19 mayalways be made atacertain uniform distance therefrom throughout thewhole length of the sole.

In this machine I employ two presser-feet, d 0, one at each side of thefeed-wheel E. The one, 6, at theinner side of the said whcel,next thebeveling-cutterf, is held in a yielding manner by the spring 6 Thefeed-wheel E, preferably serrated at its edge, is connected directlywith the end of the shaft B, (see Fig. 4,) the said shaft at its forwardend being supported in a movable bearing, g, acted upon by a spring, g,controlled as to its strength by a spring-regulator, shown as a screw, gThe force of the spring 9 is less than that of the spring D, thuspermitting the feed-wheel E to rise more or less, accordin g to thevarying thickness of the stock, without lifting the forward part of thearm A, and with it the channel-cutter c.

The edge-beveling cutterf (shown in detail, Fig. 2) has its shankconnected, by screw f with the blade-carrier f fitted into a slot orgroove in the end of the carriage 1", the said carriage being looselyattached, bya headed bolt, f to a guide-block, h, the said bolt f beingextended loosely through the curved slot h (see Fig. 7) in the saidguide-block. This carriage f is provided with pins 10 12, (see Fig. 4,)having rolls 20, (see Fig. 8,) which are extended into the circulargroove 13, made in the guide-block h and connected with the carriage orwith the screw h thereon is a link, h which at its lower end will beattached to a suitable treadle. The tail-piece 7c of the carriage willstrike the adjusting-screws 15 16 as the carriage is moved in one or theother direction in its curved path, the said adjustingscrews being setto correspond with the thickness it is desired to retain for the edge c'of the sole being operated upon. The screws 15 16 will be set to limitboth the upward and downward positions of the carriage f for bevelingcutter or blade f, to thus enable the said blade to cut the edge of thesole at the proper inclination about its fore part and in the shank.

The holder f is made horizontally adjustable by means of the screws 1,(see Fig. 2,) and by it and the screw 1 the holder may be held firmly inadjusted position.

When the carriage f is moved to lower the in its elevated position, orwould cut away the edge of the sole so much at the shank as to strikethe support All this difficulty is obviated by moving the supportlaterally, as the blade f and its carriage, disconnected from thesupport and from the parts carrying the channel-cutter and feed-wheel,is moved, as described, in a curved path.

The carriage f, as it will be noticed, has its fulcrum f movable orvariable in position,

. so the carriage and blade f do not oscillate or move in the are of acircle about a stationary or fixed fulcrum. This variable fulcrumaffords greater facility in controlling the bevel about the edge of thesole.

' The inclination at which the channel is cut,

into the sole may be varied by moving the cutter 0 about the shank b, orby turning the said shank more or less, the screw 1) holding it inadjusted position.

The nut w may be turned more or less on the lower end of rod d whichwill be screwthreaded, to thus enable the force of the spring D toberegulated.

The bevel 00 about the face part of the sole is shorter and more abruptthan the bevel 00 about the sole at the shank. (See Fig. 6.)

I claim- 1. The beveling-cutter f, shaped as shown, and its carriage,pivoted and guided as described, combined with the adjustable stops, tocontrol the upward and downward positions ofthe beveling-cutter whenbeveling the sole at different angles, as described, about its fore partand its shank, substantially as described.
